I do understand the WAN optimization as a site to multiple site and perharps the limitations applicable to a WISP environment, all the same if any kind of bandwidth savings can be achieved here, its worth it.
Moving forward, I take it that a high high config is better for my kind of deployment but when switching to plus, a better CPU say i7 or xenon will be better? Right, got that.
At the moment, I am only testing with an E1 (1mbps), however on migrating to Plus, I'll be using a DS3(45mbps). I guess I'll be contacting then for the low level setting and all...
